TAKE-UP DEVICE FOR SPECIFICATION forming part of Letters Patent No. 451,446, dated May 5, 1891i Serial'No. 230,596. (No model.)

To all whom it may concern.-

Be it known that I, JOHN AUREDENN, a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Take-Up Devices for Knitting-lylachines, of which the following is a specification.

The several features of my invention and the advantages arising from their use, conjointly or otherwise, will be apparent from the following description.

In the accompanying drawings, forming part of this specification, Figure 1 is a perspective view of the preferred form of my device. Fig. 2 is a top view of my device. Figs. 3 and 4 are detail views in perspective of parts of my device. Fig. 5 is a top View of another form of my device. Fig. 6 is a top view of preferred form of shaft used in the device shown in Fig. 5. Fig. 7 is a view in elevation of the base-plate. Fig. 8 is a view in perspective of a modified form of the front end of the base-plate.

The base A is a plate which supports the operative parts of the device and may be attached to any convenient support. It is provided with lateral standards B B, in which the shaftD is journaled, one of the standards being preferably cut out, as shown in Fig. 7, to permit of the shaft being easily inserted. The cap 0 is slipped over the standard B and serves to keep the shaft D in position. The spiral spring E surrounds the shaft D and has one end attached to the shaft,- while the other end e gets a bearing on the plate A. To prevent the end 6 of the spring from interfering with the yarn, I preferably provide the plateAwith the opening a, through which the end 6 of the spring E projects. The arm F, provided at its outer extremity with the loop f, is rigidly attached to the shaft D at any convenient point, preferably near the center. The sleeve G is slipped over the shaft D on the opposite end from the spring E. This sleeve fits loosely on the shaft. The inner end of the sleeve G is provided with a flange g, which extends under and beyond the arm F. The foot G extends from the sleeve G or flange g under and behind the shaft D, and rests on the plate A when held there by the spring II. The spiral spring H surrounds the sleeve G and has one end attached to the shaft D, while the other'end 7L presses downwardly on the foot G.

' The rear end of the plate A is provided With an eye a and the front end of the plate with an eye (1 At the front of the plate there is also placed the loop A. Instead of the opening a and loop A, there may be employed the upturned lip a provided with an opening a", as shown in Fig. 8.

The mode of operation of the device is as follows: The yarn Y is first passed through the eye a, under the foot G, and through the loop A, loop f, and eye a in the order named; or the yarn may be passed as shown in Fig. 8. The spring E tends to throw the arm F backward and the spring I-I presses down the foot G onto the yarn, holding it against the plate A with a force equal to the tension of the spring H. When traction is made on the yarn Y, the arm F is pulled down, but no yarn is drawn from the bobbin until the arm F strikes against the flange g, when the sleeve G turns slightly on the shaft D and the foot G is lifted, allowing the yarn to slip under it. In ordinary circular knitting a take-up is not necessary; but in knitting heels and toes a device to take up the slack becomes necessary. In my device this is accomplished by the arm F, which is thrown back by the spring E and takes up the slack in front, it being prevented from drawing yarn from the bobbin by the tension-foot G, which comes into play as soon as the arm F has reached a slight elevation. The use of the eye a is to keep the free end of the yarn at the front of the device and to prevent the yarn dropping to the side of the plate A. Then the yarn drops to the side of the plate A and the arm F is thrown far back, the line of traction is liable to fall below instead of above the shaft -D, and consequently to prevent the operation of the device. This is avoided by the use of the eye a To render the tension adjustable I modify the device slightly, as shown in Fig. 5. In the said figure the wheel L is centered on the shaft D, turning loosely thereon and held in place by the shoulder at. It is provided with an angular hub Z, which fits between the edges of the cap C, and thus prevents the wheel turning with the shaft D. Instead of attaching the end 6 of the spring E to the plate A, it is now made to bear against a pin Z, projecting from wheel L. The other end of the spring E is secured to the shaft D. A convenient means of attaching the spring to the shaft is to provide the shaft with the long slot (Z, (shown in Fig. 0,) through which the end of the spring passes when the spiral is slipped over the shaft.

In the form of the shaft D shown in Fig. 3 the slots (Z' and (Z to receive the ends of the springs II and E, need only be cut slightly into the ends of the shaft, as shown.

The mode of operation of the device, as shown in Fig. 5, for adjusting the tension is quite simple. The cap 0 is removed and the wheel L turned in the direction to tighten or loosen the spring, as desired, and the cap is then put back and holds the wheel L in the position in which it has been set.

Vhat I claim as new andof my invention, and desire to secure by Letters Patent, is

1. The combination of the plate A, provided with an eyelet at each end and with lateral standards, the shaft D, supported in said lateral standards and provided with take-u p arm F, and a spring for rotatingthe shaft I) backwardly, with sleeve G, surrounding shaft 1) and carrying the backwardly-projecting foot G and provided with flange g in the line of travel of the arm 1*, and a spring for rotating the sleeve G backward] y, substantially as set forth.

2. The combination of the plate A, provided with an eyelet at each end and lateral standards, shaft D, provided with take-up arm F and supported in said lateral standards, adjusting-wheel L, provided with angular hub Zand pin Z, cap O, surrounding one of the standards and forming a bearing for the angular hub Z, spring E, surrounding the shaft D and having one end attached to the shaft and the other end bearing against the pin Z, sleeve G, surrounding shaft D and provided with flange g in the line of travel of arm F, foot G, projecting baokwardly from the sleeve G, and spring H, surrounding sleeve G and having one end attached to the shaft D and the other end pressing down on foot G, substantially as set forth.
